Casey Jones

Casey Jones is a hockey-mask-wearing vigilante who first crossed paths with Raphael while prowling New York City streets, taking the law into his own hands against criminals using an arsenal of sports equipment as improvised weapons.

Few characters in comics carry the same scrappy, street-level energy as Casey Jones, who burst onto the scene in 1985's Raphael, Teenage Mutant Ninja Turtle #1 — a key issue in the Mirage universe brought to life by Kevin Eastman during the Bronze Age. Over more than four decades of comics, Casey has carved out a distinctive place in the world of the Teenage Mutant Ninja Turtles, sharing pages with the likes of April O'Neil, Splinter, Karai, and the Turtles themselves across titles like Teenage Mutant Ninja Turtles, Plastron Cafe, and the Color Classics collections. Sixty-three appearances deep and still going strong into 2026, he's a testament to how a well-drawn human presence can anchor even the most fantastical corner of comics. If you love the grittier, street-born side of the TMNT universe, Casey Jones is absolutely worth tracking down.
